To all whom it may concern:

Be it known that we, THOMAS CA ROLL, and JOHN P. FRANK,citizens of theUnited States, residing at Dayton, inthe countyof Montgomery and Stateof QOhlo, have mvented certainnewand useful Improvements inCash-Registers, of which we declarethev following to be a full, clear,and 'exact'de scription. v

Th1s lnven'tionrelates to improvements in .cash registers or accountingmachines and particularly in the mechanismv for op crating thetotalizing, printing and indie eating devices.

One of the objects of this invention is to provide a simplified form ofdifferential.

mechanism and means whereby the differential mechanism ispositivelyconnected with the main operating mechanism when the keys of the machineare pressed in.

Another object of the invention is to provide a simple and positivemechanism for resetting the t otalizer to zero by operating the machinein a certain way. This is accomplished by a resetting actuatornormallyin engagement with a pinion on the totalizer shaft and whichrotates the shaft on a resetting operation in the direction opposite towhich the totalizer wheels are r0- tated on adding operations.

Another object is to provide mechanism for printing the total shown bythe total I izer. The type carriers are normally connected positively byintermediate mechanism with the totalizer wheels so that the rotation ofthe totalizer wheels back to their zero positions on the resettingoperation carries .the type carriers away from their ing broken away.

In the drawings and the description given below a specificembodiment ofthe invention is shown applied to a cash register of the typedescribedin United States Letters Patent No. 580,378-granted Apr. 13,1897, to Cleal and Reinhard. This register is used to illustrate theinventive idea because the form of differential mechanism that it has ispeculiarly. suited to use in explaining the operation and constructionof the different improvements comprised by the invention. It is to bedistinctly understood, however, that it is not the intention to limitthe use of the invention to the particular type of register shown. asthe improvement is one that can be applied in various forms to othercash registers and accounting machines.

In the machine shown in the drawings, there is a section comprisingactuating, totalizing, indicating and printing devices alining devicesand the mechanismfor op-.

.erating'thesame.v 4

Fig. 3 Shows thediiferential mechanism;

in -one-of thebanks of the machine and the the arm 24 acting against thepin 29 will cam the plate 12 out of engagement with the cut 15 in thelocking plate 1 1- and into engagement with the lowest notch 30 in thelooking detent plate. The mechanism will be then ready for the nextoperation.

An indicator 59 is positioned by an actuator d3 having teeth 57 inengagement with an indicator pinion 53. The indicator actuator 13 andthe segment gear 1.1 are connected by links 44: and 15 swinging looselyfrom rivets 16 and 17 in the indicator actuator and registering segmentrespectively. Tllhrough these links the position that the indicatoractuator is to take is established, but the actuator is not alwayspositively placed by them, as the link 41 1 swings loose under the shaft3. After the segment 11 stopped by one of the keys as above described,the indicator actuator is positively positioned by one of a series ofarms t8 fastened to a rock shaft 4-9. This shaft has attached to it arearwardly extending arm 50. A pitman 51, reciprccated by a cam 52 faston the shaft 2, acts normally against the roll and stud 53 on the arm50, rocking tl e shaft 19. The downward movement of the pitman 51 throwsthe arm 18 up so that the roll 54, which is held by a stud 55 in the arm48 strikes the under side of the link it and moves it up until thesemi-circular cut 56 in the link rests securely against the under sideof the hub of the segment 11. The travel of the rear end of the link4L4: pushes the link 45 up, rotating the indicator actuator t3 and,through the gear teeth 57 and the pinion 58, placing the indicator 59 inthe correct position to indicate the value represented by the keypressed in or the position in which the segment gear 11 is resting.

To aline the indicator actuators and indicaters, there are providedindicator alining devices 61, one for each indicator actuator, fastenedto a shaft 60 extending across the machine. The shaft is given a rockingmovement, first clockwise and then anti-clockwise, by a pitman 63, whichis reciprocated by a cam 67 Fig. 2, acting on an arm 62 also secured tothe shaft 60. This rocking movement of the shaft moves the points of thealining devices first out of engagement with the notches 68 of theindicator actuators and then, after the actuators have been positioned.back into engagement so as to hold the actuators and the indicators 59in their correct positions.

As stated in the foregoing, the invention embodies means for resettingthe totalizer to zero by operating the machine in a certain manner. Forreasons that will be shown later on, it is necessary during thisresetting operation to disable the indicator positioning means justdescribed. The pitman 51 has an L shaped slot in its lower end in whichthe roll and stud on the arm 50 operates. Ordinarily the roll and studoperates in the shorter side 69 of the slot as shown in Fig. 1 and theindicator positioning arms 18 are operated each time the machine isoperated. When. it is desired to prevent the movement of the indicatorpositioning arms, the pitman 51 is swung back so that the long side 70of the slot is in the path of the roll and stud 53. Then as the pitman51 is reciprocated by the cam 52 the roll and stud 53 will not beengaged, but the pitman will simply move idly down and up, and theindicator positioning arms 18 will not be moved. The pitman 51 is swungback when it is desired to have it move idly, by turning the key in alock 90 (Fig. (5). The flange of the lock barrel has in it a pin 91which passes through a slot 104i in the upper arm of a bell crank lever88 which is pivoted on the shaft 1-9. In the upper end of the bell cranklever is a stud 87 extending through an elongated slot 89 in the pitman51. When the lock 90 is turned clockwise the pin 91 in the lock willrock the bell crank lever on its pivot and the pin 87 will swing thepitman 51 back so that the long side 70 of the L shaped slot will be inthe path of the roll and stud 53.

The totalizer resetting mechanism will next be described, because theconstruction of this mechanism is such that the totalizer is givencertain movements during the resetting operation that must be understoodbefore the printing, adding and transferring mechanism can beunderstood. The totalizer comprises a plurality of wheels 71 revolvingon a shaft 72 which is supported at either end by one of two arms 150fastened to a rock shaft 107. Each of the totalizer wheels has attachedto its side a turn back pawl 73 (Fig. 9) adapted to engage a notch 80 inthe shaft 72. During adding operations the totalizer wheels turn in thesame direction as the pawls 73 are pointed. For reasons that will appearlater, the shaft 72 must be at the zero position when the resettingoperation is started and in order to prevent the pawls 73 fromdisplacing the shaft during adding operations the notches 80 arenormally out of alinement with the pawls, but means are provided forshifting the shaft 79, lengthwise inde pendently f the totalizingelements loosely mounted upon it. This shift occurs at the beginning ofthe resetting operation. The mechanism for shifting the shaft comprisespins 151 and 153 (Fig. 10) on the shaft and the cam disks 155 and 1591with which the pins mentioned are respectively in contact and whichdisks are fastened to the totalizer supporting arms 150. The normalposition of these parts is as shown in the drawing, that is, the pin 151rests in the notch of the cam 155 and the pin 153 is at the apex of thecam 1. During the resetting operation the shaft 72 is turnedanti-cloelmvise (Figs. 8 and 9) and the pin 151 in the shaft engages oneside of the notch in the cam disk 155, cannning the shaft to the leftwithout moving the totalizer wheels. This brings the notches 80 intoalinenient with the pawls 73 so that the square ends of the pawls canengage the square sides of the notches. In resetting, the shaft 72 isrotated in the opposite direction ilj'ron'i that in which the wheelswere carried in adding operations and the notches 80 engage the ends ofthe pawls 73 and carry the wl' eels 71 back to the zero position wherethey will. be stopped by pins 105 on the totalizer wheels coming 111contact with the hooks on the upper end of arms 105, (Fig. 8) which arerigidly held by the shafts 0 and 107. Just before the resetting rotationof the shaft 72 is completed, however, the pin 153 on the right end. ofthe. shaft will be engaged by the surface 15c of the cam disk 15-1,shifting the shaft 72 back to the normal position and carrying thenotches 80 out of engagement with the turn back pawls 73. The notches R0are beveled at one side, as shown in Fig. 10, so that when the shaft isshifted back to the normal position these bevels will. cam. the pawls upout of the notches and upon the circumference of the shaft against whichthey rest during the adding operations.

The mechanism by which the shaft 72 is rotated is shown in Fig. 9.Attached to the left end of the shaft 72 is a broad toothed pinion 7 1which is driven. by a. segment gear 75 pivoted on the shaft 1. Thesegment gear has a pitman 76 loosely connected'to it by a rivet 77 andthis pitman is actuated by a cam 79. As the cam is revolved by the shaftto which it is fastened, the pitman 76 is carried forward, moving thesegment gear 75 first in a clockwise and then in an anti-clockwisedirection. about the shaft 1. This clockwise movement drives the pinion74- and the shaft 7 2 in an anti-clockwise direction and carries thetotalizer wheels to zero. Just before the segment gear 75 is returned tothe normal position, the totalizer is rocked down, as will behereinafter described. disengaging the gear from the segment gear andleaving the segment gear free to return to normal. position withoutaffecting the totalizer. It is, of course, apparent that the endwisemovement imparted to the shaft 72 by the cam 55 at the beginning of therotation of the shaft is not great enough to disengage the broad pinion7% from the resetting segment 7 As will be understood by referring toFig. 10, only a slight movement is necessary to bring the notches 80 inthe sl aft 72 under the pawls 73.

The resetting segment gear 75 and pinion 7 1 are normally in engagementand, as the segment gear operates each time the machine is operated onan adding operation, it is necessary to disengage them and hold them outof engagement. For this reason the shaft 107 which carries the totalizerframe is so mounted in its hearings in the machine frames that thetotaliyer can be bodily shifted back and forth laterally of the machine.This shifting is accomplished by a cam 82 (Figs. 6 and 7), which is hastened to and rotated by the shaft 2, working in connection with an arm83 attached to the totalizer frame. The rear end of the arm has a curvedsurface shaped to fit the periphery of the cam 82. In the end of the armis a plunger 05 whichengages a race 86 in the edge of the cam. As thecam is revolved in a clockwise direction by the shaft 2, the race of thecam acting against the plunger 85 will shift the totalixer to the left,thereby moving the resetting pinion 7 1 out of engagement with theresetting segment 75. hen it is desired to reset the totalizer all thatis necessary is to withdraw the plunger 85 from the cam race 86 therebyleaving the totalizer in its normal position with the resetting pinion7-41; and the resetting segment 7 5 in engagement.

The plunger is disengaged in the following manner :-l astened in theplunger 85 is a stud 97 passing through a slot 8, indicated by dottedlines, in the shifting arm 83. The bell crank lever 88 has looselyattached to it by a rivet 92, a pitman having a guide slot 94fencompassing the shaft (30. In the upper end of the pitman is a cam slot96 engaging the stud 97 in the plunger 85. lVhen the bell crank lever 88is rocked clockwise on its pivot 19 by the operation of the lock asabove described, the pitman is carried up. This causes the lower edge ofthe cam slot 96 acting against the stud 97, to draw its plunger 85 outof engagement with the cam race 86 and prevent the lateral shifting ofthe totalizcr. Tn other words, the totalizer is left in its normalposition. The pitman 93 has an extension 99 formed on it extending atright angles to and under the arm 83. In the upper edge of thisextension is a cut 101 which engages the under side of the arm 83 whenthe plunger is withdrawn from the cam race 86, and supports the arm inthe proper position for the plunger to engage in the cam race when theplunger is driven rearward by turning the lock 90 back to its normal.position.

This shifting and means for preventing the shifting also makes itpossible to print the total under the positive control of the totalizer.Attached to each totalizer ele- 'ment is a pinion normally inengagoindicator actuator is one of the sleeves 190 bearing on the otherend one of the type carriers 1101 (Fig. 13). On an adding op erationwhen the totalizer is shifted to disengage the totalizer resetting gear74 from the resetting segment gear 75, the pinion 110 is also carriedout of engagement with and into a different plane from the indicatoractuator 43 so that the indicator actuator is not affected, but when thelock 90-is operated and the plunger 85 is withdrawn from the cam, thetotalizer is left vith the gears 110 in. engagement with the indicatoractuators 13. Then when the shaft 72 is revolved in the resettingoperation the indicator actuator 43 must necessarily be rotated adistance corresponding to the distance the totalizer wheel is rotated.The distance that the totalizer wheel rotates will, of course, dependupon the distance that it has been carried from the zero position by theadding operations. For instance, if a totalizer wheel shows 5 it may besaid to be five divisions away from the zero position. In turning backto zero the totalizer wheel will be carried five divisions, moving theindicator actuator, the indicator and the type carrier correspondingdistances. In the example just mentioned the indicator and type carrierwill be positioned to indicate and print 5.

There was described above a device for positioning the indicators andmeans for disabling the positioning device. The purpose of thisdisabling device is to prevent the indicator positioning mechanism frominterfering with the positioning of the indicators by the totalizer.lVhen it is desired to reset the totalizer to zero and print the total,the machine must first be given a blank operation, that is, one in whichno registering keys are used. This will place all of the segment gears,indicators and type carriers at the zero position. Then when the lock 90is operated, the indicator positioning device is put out of commissionat the same time that the totalizer shifting device is disconnected,leaving the indicator actuators free to be moved under control of thetotalizer without the interference of the indicator ,positioningmechanism.

The totalizer elements are operated to register amounts by actuators112, which are driven by the segment gears 11. As will. be seen by Fig.1, each totalizer gear 117 and its actuator 112 are normally out ofengagement. They are also normally in different planes, (Fig. 10). Thetotalizer frame has a rearwardly extending arm 113 (Fig. 6) with a stud114 in it to hold an anti-friction roll 115 operating in a race 116 of acam 82 fastened to the shaft 2. This cam race is deep enough and theroll and stud are long enough to prevent their be ing disconnected whenthe arm 113 is car ried away from the cam 82 by the lateral shifting ofthe totalizer as described in the foregoing. As the cam 82 is revolvedby the shaft, the totalizer is rocked with shaft 107 for a pivot firstdown and then up into the position shown in Fig. 6. Just previous to thedownward movement of the totalizer it is shifted over by the shiftingmechanism described above, bringing each tota-lizer gear 117 into thesame plane as its totalizer actuator 112. Immediately after thetotalizer is drawn down into engagement with the actuators 112 theregistering segments 11 are carried up the proper distances to representthe value of the keys pressed in and as the actuators 112 and theregistering segments 11 are always in engagement, the totalizer wheelsare of course given corre sponding units of movement. Before thesegments start their down stroke the totalizer is shifted laterally,disengaging the totalizer gears from the actuators 112 and it is thenrocked up to the normal position with the gears 1.10 in engagement withthe actuators 13.

As indicated in the description given above of the resetting mechanism,the resetting shaft 72 must not be allowed to move away from the Zeroposition except during resetting operations. Means are provided forpreventing the shaft from working out of position during these shiftingmovements of the totalizer. Two pins 157 and 158 (Fig. 10) are set inthe machine frame 159 in such positions that when the total izer isshifted to the left the pin 157 enthe teeth of the resetting gear. 74and n'events any rotation of the gear and shaft. On the downwardmovement of the totalizer the gear H is brought into engagement with thepin 158 and this pin is long enough for the gear to remain in engagementwith it while the totalizer shifts to the right. When the totalizer isrocked back to its original position the gear 74 is carried clear of thepin 158, leaving the gear free to be rotated. 7

The lateral shifting and the vertical rocking of the totalizer have beenutilized in devising the mechanism for transferring from totalizerwheels of lower to wheels of higher values. Two of the sections of thetotalizer with their corresponding transfer elements are shown in Fig.10. Each totalizer element consists of the gear 110 to engage theindicator actuator 48, the totalizer wheel 71, the operating gear 117which is to engage the totalizer actuator 11.2 and a transfer trip cam118. All of these members are rigidly fastened together and looselymounted on the shaft 72 with spacing collars 119 to hold the differentsets of these members the proper distance apart on the shaft. Eachtransfer element consists of a transfer tripping plate 120 and atransfer operating plate 121, the two being rigidly fastened together ona sleeve 122 and rotatable on the shaft 142. In order to understand theoperation of this mechanism it is necessary to recall the movements ofthe totalizer. The totalizer is first shifted to the left so as to bringthe operating gear 117 into the same plane as the actuator 112. Thetotalizer is then rocked down bringing this gear and the actuator intoengagement, then shifted to the right, disengaging the gear 117 from theactuator 112, after which the totalizer is rocked back up to the normalposition shown in Fig. 10. Vhen the totalizer is shifted to the left androcked down, the periphery of the trip cam 118 will rest in the curvedupper edge of the transfer trip plate and a stud 123 will be in the pathof an extension 12% on the trip cam 118. \Vhen an amount is registeredcarrying the totalizer wheel. past the 9 position, the extension 125! ofthe trip cam will strike the stud 123 and carry it forward. The trip camhas in it a groove 126 to receive the point 127 of the trip plate andallow the plate to rotate on its shaft. As the forward movement of theplate is continued it will be drawn into the position shown in Fig. 1.2with the curve 128 riding against the periphery of the transfer trip cam118 look ing the plate in that position, while the transfer operatingplate 121 is drawn up and held in the position shown in Fig. 12. Thetransfer trip cam 118 is wide enough to hold the transfer trip plate 120in tripped position when the totalizer is shifted to the right (Fig.10), as previously described, to bring the gears 110 in verticalalinement with the transfer, operating plates 121. Mounted on ashaft-129 extending the length of the totalizer are a number of transfercams fastened to the shaft. This shaft is rotated first clockwise andthen anti-clockwise by a segment gear 1330. (Figs. 8 and 11) driving apinion 131 attached to the transfer cam shaft. This segment gear isdriven by a cam 181 which has a cam race 132 working against a stud androll 133 fastened to the upper eitensiou of the segment gear. hen theshaft 129 rotated clockwise, the

' extension 134 on the transfer cam will strike against the 1ug 135 onthe transfer trip plate. This will carry the tooth 136 on the transferoperating plate 121 up into engagement withthe transfer wheel-llt) andcarry the totalizer wheel forward one division. The totalizer is. thenrocked up out of engagement with the transfer members so that the lattercan be returned to their normal position by the transfer restoringmechanism.

The transfer restoring mechanism is shown to the best advantage in Fig.12. It comprises a rack 138 which is actuated in one direction, by a cam139 fastened to the main driving shaft 2. The lower end of the racksupported and guided by a roll 110 and the other end by a fork whichspans the shaft The teeth of the rack are in, engagement at all timeswith a pinion 1.11 securely fastened to shaft 142. Fastened to the sameshaft are transfer restoring plates 1-13. Any movement which given theshaft 112 by the rack 138 is therefore trans mitted to the plates 11:3.When the machine is first operated the cam 139 is rotated out of thepath of-a roll and stud Lt-t fastened to the rack 1338, allowing therack to move freely and preventing it from inte1= fering with themovements of the transfer operating mechanism. After the transfer hasbeen made the cam 13i).strikes the roll and stud 144C pushing the rack138 forward and rocks the shaft 142 and the transfer restoring platesl-lb in a clockwise direction. A pin 14-5 in the transfer restoringplate will strike the forward edge of the transfer operating plate 121and carry it and the transfer trip plate 120 back totheir normalposition. This description shows that the entire transfer mechanism ispositive throughout, there not being a spring used. througlmut this partof the mechanism, and the number of parts has been reduced to a minimum.

So far in the description no mention has been made of the constructionand operation of the printer. In fact, none is necessary. \Vhile Fig. 13shows the printer constructed on the Cleal & Reinhard principle, it isillustrative only. The inventive idea concerns itself with thepositioning of the type carriers, and the means for taking theimpression from the type, feeding the record strip, etc., are notinvolved in the improvement.

In summarizing briefly the operation of i the illustrative machine andthe variousinr provements embodied in it. a description will first begiven of what happens on a regular adding operation. 16.is first pressedin after which the machine can be operated by any suitable means,transmitting the power to the main shafts of the machine. Pressing inthe key operates a plunger or sliding plate 12 that positively connectsthe di'lferential mechanism with the positively operating mainmeehanism. The differentially moved segment gear 11 is carried up until.the latch is drawn forward by one of the registering keys, therebydisconnecting the segment gears and differentially moved mechanism fromthe main driving mechanism. This upward movement of the segment geardetermines the position for the indicator actuators, the type carriersattached to the indicator actuators and the indicators. These parts arethen moved into the determined positions by arms 18 moving the linkscouuecting the segment gears 11 and the indi- One .of the keys cateractuators 13. Indicator alining devices, which were drawn out ofengagement when the machine started to operate are then brought up intoengagementwith the indicator actuators, holding the actuators,indicators and type carriers rigidly in position to indicate the valueof the key just pressed. The segment 11 is returned by a pin 32 in thelocking plate 14, rigidly attached to the shaft 3, acting in connectionwith the latch. plate 12 which is forced back into engagement with thelocking plate M as soon as the pin just mentioned contacts the segmentgear 11. The key pressed in is released by the key releasing mechanismin time to position the arm 2st to disconnect the latch plate 12 fromthe locking plate 14: when the segment gear 11 reaches its normalposition. The totalizer during this time is shifted first to the left todisconnect the resetting mechanism, and the totalizer driving gears andthe totalizer actuators, which are normally in different planes, arebrought into alinement. The totalizer is then rocked forward and down sothat the totalizer operating gears are brought into engagement with thetotalizer actuators. The actuators 112 are always in mesh with thesegment gears 11. Just after the totalizer operating gra rs are meshedwith the actuators, the registering segments 1.1 begin their upwardtravel, driving the totalizer wheels the proper number of divisions torepresent the value of the keys pressed in. It is at'this time that thetransfer elements are tripped, if there is a transfer to be made fromone totalizer wheel to the wheel of next higher value. The totalizer isthen shifted to the right bringing the transfer operating plates intoalinement with the transfer gears 110 and the transfer operatingmechanism then completes the transfer. then rocked back up to normalposition and the transfer mechanism is restored to its normal positionby the restoring mechanism provided.

lVhen it is desired to reset the totalizer to zero and print the totalit is necessary to first make a blank registration. This is to inkingthe indicators and type wheels to their more positions. The lock 90 isthen operated,

The totalizer is shifting the pitman 51 so that the devices for 1positioning the indicators will not be moved during the resettingoperation. Operating the lock 90 also disconnects the totalizer shiftingmechanism so that the totalizer will remain in its normal position, thatis, in engagement with the indicator actuators. The resetting mechanismrevolves the shaft 72 on which the totalizer wheels are mounted and thisshaft 72 is cammed laterally at the beginning of the rotation to bringthe resetting notches 80 first into alinement and then into engagementwith the ends of spring pressed pawls 73 attached to the wheels.

Continued rotation of the shaft carries the wheels back to zero and camsthe shaft 72 back to its normal position. The distance that eachtotalizer wheel is turned during the resetting operation dependsentirely on the distance it has been carried. away fro-m the Zeroposition by the adding operation. The backward rotation of the totalizerwheels is transmitted through the indicator actuators 43 to the typecarriers and indicators, causing them to be carried away from their Zeropositions the same number of divisions that the corresponding totalizerwheels are rotated in returning them to their zero position. In otherwords, the amount shown by the totalizer wheels is transferred, as thetotalizer is carried to Zero, to the indicators and the type carriers.After the type carriers are positioned the printer vopcrating mechanismtakes an impression from them on the record. strip.
